Following the steady demand growth and diminishing generation capacity margin due to lack of generation investment, Slovenia is already importing almost a quarter of electricity needed to cover its demand. Coupled with the deregulated electricity market and the European Union (EU) climate change mitigation measures implemented through EU Emissions Trading Scheme (EU ETS), the economic as well as environmental...
As the security assessment of power production is a complicated multi-attribute evaluation problem, this paper applied the gray target assessment model of gray system theory to the security assessment of power production according to the system engineering theory. And using optimization theory and Jaynepsilas maximum entropy principle a method of determining the linear combination weights based on...
This paper applies two methods to evaluate the economic effects of the policy of "replacing small units with large ones (RSWL)," one is Discounted Cash Flow (DCF) method which performs a technology economic analysis both from the financial and the economic perspectives, the other one is to use the Real Option theory to study the lagging investment problem of the big unit. Through an illustrative...
Since the second half of 2007, the coal price in China has witnessed dramatic growth, the generation cost has gone up and power generation companies have got huge benefit losses. This essay analyzes the major reasons of coal price increase in China, predicts the future tendency of steam coal price and proposes policy suggestion to deal with rapid growth of coal price.
The paper adopts rough set reduction algorithm to reduce the influence factors of power plant selection and eliminate the uncorrelated attribution, through which we can obtain typical samples. After this, adopting fuzzy method to calculate the membership degree of the typical samples, which are looked on as the input of BP Neural Network and the expert values are as the expected output to train the...
Inventory control is an important aspect of production logistics management in power system. According to the characteristic of raw material purchase and stock, the paper puts forward an optimal inventory model to minimize the cost. A novel hybrid chaos immune evolutionary optimization algorithm (HCIEOA) of solving the minimal purchasing cost problem is presented. This algorithm integrates space-searching...
Electricity futures exchange is usually regarded as a valuable way to reduce price volatility of electricity market, but its risk to the equilibrium of the market is almost neglected; therefore, it is impossible to find out a workable approach to avoid the impact from supply and demand to electricity market. However, it is so important that it should not be avoided. In view of the case, this paper...
With the development of electricity market reformation in China, it is especially important to evaluate the competition competence of power generating enterprises. Based on the characteristics of their, this paper bring forwards an index system to evaluate the competition competence of power generating enterprises. SVMs are widely used in load forecasting and bioinformatics systems. Conventional methods...
